Article Synopsis
- The research focuses on recovering three types of volatile organic compounds (VOCs): acetone, dichloromethane, and ethyl formate, using a method called temperature swing adsorption (TSA) with activated carbon.
- The process includes adsorption of vapors followed by regeneration using hot nitrogen, where a Factorial Experimental Design (FED) is employed to optimize conditions for maximum efficiency at a reduced cost.
- Validation of the experimental results with a simulation model (PROSIM) showed a small error percentage, indicating good correlation between experimental and simulated data.

Article Synopsis
- The study investigated the regeneration of dichloromethane from activated carbon using hot nitrogen and steam, focusing on performance and cost.
- A Factorial Experimental Design (FED) was used to optimize the temperature and velocity of nitrogen for maximum regeneration efficiency, with results validated by the PROSIM simulation model, showing an average error of 2.6%.
- Both regeneration methods achieved an 84% recovery rate of dichloromethane, with the choice between them depending on factors like regeneration time, costs, and product purity.

Article Synopsis
- Organic vapors from industrial processes can be effectively captured using activated carbon beds, which help in reducing environmental pollutants.
- Two regeneration methods—thermal desorption with hot nitrogen and vacuum depressurization—can be used to recover these trapped vapors and may be combined for enhanced efficiency.
- An experimental design identified optimal conditions for desorption, which led to an 82% recovery rate of dichloromethane and reduced cooling time of the carbon bed between cycles.
